Overall a decent purchase

Pros:

Very solid. I am 6' 2" 230lbs and have been training for 15yrs and feel comfortable on this machine regardless of how heavy I go.



Great range of excercises that can be performed. the top attachment allows me to place the wide grip bar included in it and perform chinups. The footbar for seated cable rows also allows support to do situps.



Minimal footprint. fits in the corner of my bedroom.



Cons:



Sparse directions. I am fairly machanically inclined but had trouble with the direction which was basically just a diagram. The completion of the pulley system should have had it's own set of directions.



Too short for taller users. If you are over 6' like me you will have trouble with the range of motion not being long enough on back excercises. I believe in a very full range of motion and sometimes have trouble even at the gym though.



Friction. The attachement for the weight slides along grabs preventing a smooth movement as one would be accustomed to from the gym. I'd noticed the gym machines have a fitting for a gease gun to keep their weight attachments lubricated. I greased the bar the weight attachement slides along and viola it eliminated much of the sticking and the movement was better. Again no mention of this in the directions.



Overall I am happy with my purchase and use my machine regularly. If I could change one thing I would lower the seat 2 to 3 inches which would eliminate the range of motion problem for taller lifters.
